Engine Wiringharness replacement
My PCM and Throttle control module was torn off the vehicle so many of the wires are switched or lost... I am curious if anyone knows what it all takes to replace the entire harness, or I'm thinking just soldering the ends of the new harness onto the old one. Opinions?

NO!! Pull the intake manifold off and you have good access to all that you need to access. The harness replacement is NOY that difficult! There are TWO harness clamps that are secured with a 15MM hastener and one ground wire on the drivers side head at the rear of the head.

Pull the battery out and you should be able to run most of the wiring. I would also recommend pulling the passenger fender off to make it easier to get the PCM / TAC module wiring in correctly.
